what are oxidation, reduction and redox reactions give one example each
Answers
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
1.The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. ... In the course of this reaction, each magnesium atom loses two electrons to form an Mg2+ ion.
2.Reduction can be considered as the removal of oxygen, the addition of hydrogen, or the gain of electrons. Removal of oxygen: Metal ores which are oxides are reduced to the metal - this is how iron is made from iron ore. The reducing agent is carbon monoxide.
3.An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. The formation of hydrogen fluoride is an example of a redox reaction. We can break the reaction down to analyze the oxidation and reduction of reactants
